7 Claims. (Cl. 22283) This invention relates to a dispensing device, andespecially to adispensing devicefor receptacles which have to behermetically closed during storing.

For storing volatile fluid or gaseous mediums such as poisonous liquidsor gases, i. e. condensedgases, medical goods, inflammable substances,cooling agents and fire extinguishing means in such a manner that anyloss through leakage or any contact with the atmosphere or othersubstances can be avoided, it .is known to use hermetically closedreceptacles or containers Which instead of having an ordinary .cock vorvalve which maybecome more .or less leaky, is provided with .an outletwhich is blocked by a tight preferably metallic blocking wall welded orsoldered to the outlet, and .whichcontainers are further provided withelements which can be operated from the outside of the receptacle orcontainer to cut or punch through the blocking wall when the receptacleor container isto be emptied.

:Further, it is known to usehermeticallyclosedreceptacles or containersprovided interiorly thereof with an opening member which by adeformation of one of the end bottoms of the container displaces thesaid member against the second end bottom so that the member in the lastmentioned end bottom makes a hole through which the contents of thecontainer may then be emptied. Such containers are, however, onlysuitablefor use once and are generally thrown away after having beenemptied. Further it is difficult to provide a hermetically closedconnection between a such receptacle and a receiver for its contents.

An object of the present invention is to provide a comparatively easilyexchangeabledispensing device, particularly for use in connection withhermetically closed receptacles or containers as mentioned above; thedispensing device serves to close the receptacle or container duringstoring and to one emptying thereof; the dispensing device may bemounted on the receptacle or container before or after its filling withthe medium to be stored.

Another object of the presentinvention is to provide a dispensing devicewhich assures a hermetical closing of a receptacle during storing butnevertheless facilitates access to the contents thereof and emptying ofthe-receptacle without the receptacle being disturbed.

A further object of the present invention is toprovide a dispensingdevice which assures a hermetical closing of a receptacle during storingbut-nevertheless makesit possible in a simple manner to produce ahermetically closed connection between the receptacle and a receiver forthe contents thereof, which connection can be rendered effective afterits establishment.

Still another object of the present invention isto provide a dispensingdevice with self-contained opening means which can be rendered effectivethrough medium of pressure applied on said outletclosure from theexterior thereof.

A still further object of the present invention is to provide adispensing device which in a tightfitting manner States Patent can beconnected not alone to a receptacle but simultaneously to a receiver forthe contents of the receptacle and which has self-contained means forproducing connection between the receptacle and the receiver only byapplication ofpressure on the outlet closure.

Another object of the present invention is to provide a dispensingdevice which assures hermetical closing of a receptacle but neverthelessa simple opening thereof when its contents has to be used, and which maybe manufactured independently of the receptacle for which it isintended.

Still another object of the invention is to provide a dispensing devicefor hermetically closed receptacles, which closure is simple to open,comparatively cheap to produce and easily can be arranged on and anewremoved from the receptacle, so that after use it may be thrown away.

With this and other objects in view the invention relates to adispensing device in which a housing, the walls of which are entirely orpartly made from a comparatively easily deformable material, is insimilarity with a valve housing provided with inlet and outlet openingsof which at least one opening is closed or blocked by means of apierceable blocking wall, and in which the housing interiorly isprovided with an opening member having a cutting edge facing theblocking wall and being arranged with its cutting edge to punch or cutthrough the blocking wall when the housing is compressed.

The invention will now be described more in detail with reference to theaccompanying drawings illustrating by ways of examples embodiments ofthe invention.

In the drawings:

Fig. 1 is a longitudinal sectional view of an embodiment of thedispensing device with a straight passage, in closed position,

Fig. 2 is a corresponding longitudinal view of an only slightly amendedembodiment of the invention in open position,

Fig. 3 is a section taken on line 33 in Fig. 1, and

Figs. 4 and 5 are longitudinal sectional views corresponding to Figs. 1and 2 of another embodiment of the present invention having an angularpassage.

In the embodiment of my invention shown in Figs. 1 and 2 10 indicates aball-shaped or lens-shaped housing of a deformable material such asbrass, copper, soft sheetmetal, plastic or the like materials. Thishousing it comprises two diametrally disposed pipe-shaped branches l2and 14, of which the branch 12 is closed in a tight-fitting manner bymeans of a thin blocking wall 16 preferably made from the same materialas the housing 10. This blocking wall 16 may, when desired, withoutdiificulty be punched or cut through by means of an opening member orpiercing tool 18 consisting of a pipe section 20 one end 22 of whichextending into the branch 12 has been obliquely cut off thus forming acutting or piercing edge 24, facing the blocking Wall 16. The other end26 of the piercing member 18 is secured to or loosely disposed disposedin the branch 14. The branch 12 extends in the embodiment shown into andis for example by means of a packing 28 or by soldering in atight-fitting manner connected to an outlet pipe 30. The branch 14receives and has secured to it in a tight'fitting manner for example bymeans of a packing 32 or by soldering the free end of an outlet pipe orneck 34 of a receptacle 36 for storing of a medium which is later to beemptied through the dispensing device. The neck 34 extends up to andabuts against the end 26 of the opening member 18, which as will beespecially seen in Fig. 3 is provided With a lengthwise slot 38 at itstop.

In Fig. 1 the dispensing device is illustrated in its normal blockingposition in which the cutting edge 24 of the member 18 is positioned inimmediate vicinity of the blocking wall 16 in the end of the branch 12.The dispensing device is opened by compression, namely by means of apair of tongs or another simple tool, which moves member 18 from theposition shown in Fig. 1 to the position shown in Fig. 2, whereby theopening member 18 abutting against the neck 34 is axially displaced,whereby the cutting edge 24 pierces the wall 16 by cutting out a disc4-9 from the wall, said disc having a diameter corresponding to theouter diameter of the member 18.

The disc 40 is released from the wall along its entire circumferencesave the portion disposed opposite the slot 38 in the opening member 18by means of which portion the disc 40 remains connected to the wall 16although bent upwards as indicated in Fig. 2. Thus, there is provided afree passage for the medium in the receptacle 36, which medium flowsinto and through the opening member 18 and continues through the holeprovided in the blocking wall 16 and the discharge pipe 30 which issupposed to be axially displaceable together with the branch 12 of thehousing 10.

The above described dispensing device can also be arranged in such amanner that the branch 12 of the housing 1 is connected to thereceptacle 36 and the branch 14 to a discharge pipe.

As to all essential the embodiment shown in Fig. 2 corresponds to theembodiment shown in Fig. 1, but it differs slightly from the latterthereby that between the neck 34 of the receptacle 36 and the end 26 ofthe opening member 13 an abutment ring 4-2 is inserted in and connectedto the branch 14. This abutment ring assures the displacement of theopening member 13 during the compression of housing 10 independent ofthe placement of the neck 34 in the branch 42. Since this abutment ring42 prevents a backward displacement of the opening member 18, it is notnecessary that the neck 34 is inserted in the branch 14 as shown, butthe branch 14 may be inserted in the neck 34 in a pluglike manner.

The outlet closure shown in Figs. 4 and 5 comprises a housing ofordinary, not compressible material, such as casting. The housing isopen at the top where it is covered in a tight-fitting manner by adomed, for instance a semiglobular cover or cap 44 of a deformablematerial. One end of the tubular opening member abuts against or issecured to the inner side of the said cover or cap, whereas the otherend of member 18, which end is provided with the cutting edge 24,extends down into and is guided in the tubular branch 12 projecting fromthe bottom of the housing 19, and which is slightly closed by theblocking wall 16 immediately in front of the cutting edge 24. The branch12 extends down into and is tightly connected to a sleeve 46 on anoutlet pipe 48. The housing 10 is on one side provided with a branch 14which can be connected to a pipe or a tubular neck 34 or the like on thereceptacle 36 for the medium.

in Fig. 4 the outlet is shown in blocking position and in Fig. 5 in openposition, in which the opening member 18 has been axially displaced by adownwardly directed pressure on the cover or cap 44 and has pierced theblocking wall 16 in a manner corresponding to the one described inconnection with the embodiments shown in Figs. 1 to 3. The medium willnow flow from the container to the housing 10 and continue through theslot 38 into the tubular opening member 18 from where it leaves throughthe pipe 48. The emptying may also take place in the opposite directionif the branch 12 is connected to the receptacle instead of the branch14.

With regard to the nature and the quantity of the medium to betransferred from a container to a receiver for the medium within thescope of the appended claims the dispensing device according to thepresent invention may be shaped in many other ways than described above.
